Description

Technical Field

[0001] The utility model relates to the technical field of lifting platforms for plate processing machines, in particular to a lifting platform for plate processing machines. Background Art

[0002] During the plate punching process, the plate needs to be accurately stepped from a low position to a high position so that the plate can be processed at a precise high position. The lifting platform in the existing technology drives the lifting platform to move along the track through a single driving point. Since the single driving point can only act on a certain point of the lifting platform, and the span of the lifting platform is relatively large, in this case, it is easy to cause errors in the movement of various parts of the lifting platform and the driving point, thereby affecting the processing of the plate.

[0003] In this regard, China has filed patent application number CN201620804049.7, which discloses a lifting platform for a plate punching machine. The lifting platform includes a lifting platform and a lifting power mechanism. The lifting power mechanism is characterized in that it includes a motor with a driving pulley fixed to a frame, a transmission belt driven by the driving pulley, and lifting components with transmission pulleys arranged at the four corners of the lifting platform. The lifting mechanism includes a bracket fixed to the frame, an upper bearing seat with bearings arranged on the bracket, a lower bearing seat with bearings, a screw rod rotatably connected to the two bearings, a screw rod sleeve screwed onto the screw rod, and a connecting frame fixed to the screw rod sleeve. The lifting platform is fixed to the connecting frame, the transmission pulley is fixed to the transmission shaft of the screw rod, and the transmission belt is wound around the driving pulley and the transmission pulley. Compared with the existing technology, this utility model has the advantage of being able to precisely step and raise and lower the lifting platform.

[0004] The lifting platform uses a transmission belt to drive four sets of screw rods to rotate, so as to simultaneously lift the four corners of the bottom surface of the lifting platform, making the lifting activity of the lifting platform more stable. However, due to the use of a transmission belt, the transmission belt will undergo elastic deformation during use, making it impossible for the four sets of screw rods to rotate simultaneously, which in turn affects the lifting stability of the lifting platform.

[0005] Therefore, in order to solve the above problems, a lifting platform for a plate processing machine is proposed. Utility Model Content

However, due to the use of a transmission belt for transmission, the transmission belt will undergo elastic deformation when in use, so that the four sets of screws cannot be guaranteed to rotate simultaneously, which in turn affects the lifting stability of the lifting platform.
